Tamu XGBoost Regression Model

Overview

The Tamu Regression Model is part of the Soulprint archetype system, designed to measure expressions of lightness, uplift, and shared resonance in text.
It was trained on a balanced dataset of 912 rows, evenly distributed across three continuous output bins:

• Low (0.00–0.33): minimal energy, muted or subdued responses
• Mid (0.34–0.66): moderate energy, rhythmic or collective responses
• High (0.67–1.00): elevated energy, loud or vibrant expressions

The model outputs a continuous score between 0.00 and 1.00, where higher values correspond to stronger expressions of Tamu energy.

Usage

Inference Example

import xgboost as xgb
from sentence_transformers import SentenceTransformer
from huggingface_hub import hf_hub_download

# -----------------------------
# 1. Download model from Hugging Face Hub
# -----------------------------
REPO_ID = "mjpsm/Tamu-xgb-model"
FILENAME = "Tamu_xgb_model.json"

model_path = hf_hub_download(repo_id=REPO_ID, filename=FILENAME)

# -----------------------------
# 2. Load model + embedder
# -----------------------------
model = xgb.XGBRegressor()
model.load_model(model_path)

embedder = SentenceTransformer("all-mpnet-base-v2")

# -----------------------------
# 3. Example prediction
# -----------------------------
text = "Inside the library, the pages turned slowly as students whispered."
embedding = embedder.encode([text])
score = model.predict(embedding)[0]

print("Predicted Tamu Score:", round(float(score), 3))
